How to return a value greater than zero?

Question

On line 11 in app.js, implement the isUsernamePresent function. Return true if the user name length is greater than zero.

I received this message. Bummer! There was an error with your code. Syntax error. I don't see the error, since I copied the code exactly, from within my workspace.

js/app.js

//Problem: Hints are shown even when form is valid
//Solution: Hide and show them at appropriate times
var $password = $("#password");
var $confirmPassword = $("#confirm_password");
var $username = $("#username");

//Hide hints
$("form span").hide();

function isUsernamePresent() {
if($username.val().length > 0)
}

function isPasswordValid() {
  return $password.val().length > 8;
}

function arePasswordsMatching() {
  return $password.val() === $confirmPassword.val();
}

function canSubmit() {
  return isPasswordValid() && arePasswordsMatching();
}

function passwordEvent(){
    //Find out if password is valid  
    if(isPasswordValid()) {
      //Hide hint if valid
      $password.next().hide();
    } else {
      //else show hint
      $password.next().show();
    }
}

function confirmPasswordEvent() {
  //Find out if password and confirmation match
  if(arePasswordsMatching()) {
    //Hide hint if match
    $confirmPassword.next().hide();
  } else {
    //else show hint 
    $confirmPassword.next().show();
  }
}

function enableSubmitEvent() {
  $("#submit").prop("disabled", !canSubmit());
}


function usernameEvent() {
  if(isUsernamePresent()) {
    $username.next().hide();
  } else {
    $username.next().show();
  } 
}

//When event happens on password input
$password.focus(passwordEvent).keyup(passwordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

//When event happens on confirmation input
$confirmPassword.focus(confirmPasswordEvent).keyup(confirmPasswordEvent).keyup(enableSubmitEvent);

$username.focus(usernameEvent).keyup(usernameEvent).keyup(enableSubmitEvent);

enableSubmitEvent();

function isUsernamePresent() {
if($username.val().length > 0)
  //no return specified<---
}

also instead of using an if statement you can return the bool itself

function isUsernamePresent() {
  return ($username.val().length > 0);
}

if length>0 it will return true
